Thailand: Electronic Transactions Development Agency adopted regulatory clarifications on obligations of high-risk platforms subject to additional duties under DPS Act

On 31 July 2025, the Electronic Transactions Development Agency (ETDA) issued regulatory clarifications for online marketplace platforms, following the issuance of the list of high-risk platforms subject to additional obligations under the Royal Decree on Digital Platform Service Businesses Requiring Notification B.E. 2565 (2022) (DPS Act). The list includes 19 digital platform service providers designated as high-risk under Section 18(2) of the DPS Act, based on risk criteria including financial and commercial stability, electronic data system reliability, potential for public harm, and high-level impact. These platforms are subject to compliance with Section 20 of the DPS Act, effective from 10 July 2025, which imposes additional procedural and technical obligations. These include mandatory identity verification for registration as operators or sellers, disclosure and vetting of seller information, enforcement of product standards, implementation of policies for product and seller governance, establishment of user complaint mechanisms with resolution notification within three days, and transmission of seller data to competent government agencies upon request. ETDA also clarified the criteria for high-risk designation, which include exceeding 100 million baht in transaction value within Thailand, operating without Department of Business Development (DBD) registration while having at least 100 business users, an average monthly active user (AMAU) rate exceeding 5% of the population, or lack of effective user supervision enabling unlawful or harmful activities. The forum also addressed inter-agency coordination with the Thai Industrial Standards Institute (TISI), Food and Drug Administration (FDA), and the Office of the Consumer Protection Board (OCPB), data linkage protocols, information credibility standards, and the 180-day transitional period from the Royal Gazette publication to operational enforcement.
